Problems solved by technology

And no copper layer glass silver mirror does not plate metal copper, does not produce ferrous sulfate, but with common glass silver mirror mirror back paint, as disclosed " based on the quick-drying high solid content coating of modified alkyd resin " of CN1371409A, A kind of acrylic acid modified alkyd resin composition cured at room temperature; or CN1621430 disclosed "modified dry oil alkyd resin and curtain coating for mirror back metal coating protective coating", a kind of dry oil modified Alkyd resin, modified acrylic acid and modified epoxy resin, will make the edge of the copper-free glass silver mirror black, and the silver-plated layer without copper layer protection is easy to change color after over-baking
[0003] To sum up, the environment-friendly copper-free glass silver mirror cannot use ordinary glass silver mirror mirror back paint, and the silver-plated layer without copper-coated layer cannot be overbaked, otherwise the performance of the glass silver mirror will be affected

Abstract

The invention discloses a making method of single-painting typed copper-free layer glass back paint, which comprises the following parts: 7.0-8.0wt% metal oxide, 9.0-11.0wt% ultra-fine talcum powder, 15.0-37.0wt % ultra-fine barium sulfate, 20.0-30.0wt% short-oil alkide resin, 3.0-10.0wt% coloring dye, 0.05- 0.15wt% anti-crust agent, 0.01-0.08wt% drier, 0-3.5wt% glossing agent and organic solvent.

Description

Technical field: [0001] The invention relates to a preparation method of a paint, in particular to a preparation method of a single-coated copper-free glass silver mirror back paint. Background technique: [0002] The production method of the ordinary glass silver mirror is to first coat a layer of metallic silver on the glass surface with a silver mirror chemical reaction method as a reflective layer, and then use a copper mirror chemical reaction method to coat a layer of metallic copper to increase the reflection effect of the silver film. and protective effect. In order to protect the metal layer of the glass silver mirror from chemical corrosion and physical damage, primers and topcoats need to be coated on the metal layer of the glass silver mirror to protect the metal layer, and the chemical reaction of the copper mirror will produce ferrous sulfate which is not friendly to the environment . And no copper layer glass silver mirror does not plate metal copper, does n...
